# P Value From Z Score Examples

P-value is used in statistical hypothesis testing, specifically in null hypothesis significance testing. From the below P value from Z Score examples you could see that left-tailed P value is Z < 1 and right-tailed value is Z>1 and two-tailed value is |Z| > 1. You should use the values for Z score between -6 and 6.

##

###### Example 1:

Let us consider the problem: What is the P value from Z-Score 0.05?

###### Solution:

We can calculate the P values using the given formula.

To find the P-value from Z-score, you need to use a **Z-Score table**.
**Given Z-score**: 0.05,
**Left-tailed P-value**: p(Z > z)
By using the Positive Z-score table, We get
p(Z > 0.05) = 0.5199

**Right-tailed P-value**: p(Z < z)
p(Z < 0.05) = (1 - (Left-tailed value))
p(Z < 0.05) = 1 - 0.5199
= 0.4801

**Two-tailed P-value**: (|Z| > 1)
Two tailed P value = ((Right-tailed P-value) x 2)
0.4801 x 2 = 0.9601

**Two-tailed Confidence Level**: (|Z| < 1)
= 1 - 0.9601
= 0.0399

**Therefore, the value of P value from Z score is 0.9601**
